The U.S. Department of Energy (DOE) is proposing to provide funding to Obermeyer Hydro Accessories, Inc. to design a cost effective, small-scale, adjustable speed, pumped storage hydro (AS-PSH) system optimized for U.S. energy storage requirements. The proposed project would be divided into two Budget Periods (BP), with a down-select between the two budget periods. This NEPA review is for BP1 only.

BP1 would involve scalability analyses, cost assessments, and feasibility work to be completed at Obermeyer’s facilities in Wellington, CO. BP1 activities would be limited to intellectual, academic, or analytical activities and would require no physical materials beyond standard office supplies and computer equipment.
